Kolar Labs mixed bed DI Deionization Resin blend is the perfect solution for aquarium systems and other applications where ultra-pure water is required. The nuclear grade, mixed bed resin is prepared from component anion and cation resins which have been manufactured with the highest degree of purity and converted to the H+ / OH- form.

Use after your RO membrane to reduce total dissolved solids (TDS) to zero in your RODI system. We offer standard (non-indicating) and color-changing (indicating) formulations. The indicating resin changes from purple to clear once exhausted for a visual indication of resin condition. The non-color indicating retains its beige color through exhaustion, and saves you money if you already monitor TDS which is the most accurate approach for consistent ultra-pure water production.

Use the ultrapure water from your RODI system after remineralization for your freshwater, brackish, saltwater, reef or marine aquarium or tank. RODI treatment processes are ideal to remove all minerals and contaminants present in your source water.

Kolar Labs is the exclusive distributor for Lanxess Lewatit^® NM-65 DI Resin Indicator (color indicating) and Lanxess Lewatit^® NM-60 DI Resin to the aquatics industry in North America. From the same trusted German manufacturer, Lanxess, that has made our GFO Bayoxide® E33 and E33HC GFO products.

How to Purify Your Water

1. 567g (1.25lb) fills one standard 2 ½ inch wide by 10-inch tall refillable cartridge (also available), packed tightly.
2. For best efficiency, use TDS monitor or indicator resin to monitor rise in TDS post treatment. Change resin upon exhaustion.
3. For the aquatics industry, best used after reverse osmosis (RO) for zero TDS water.
4. If chloramines are present in source water, pre-filter with catalytic carbon or carbon block to extend the life of the RO membrane and DI resin.
5. Remineralize your water with freshwater or saltwater salts prior to use in your aquarium or aquatic environment.
